How many miles of long trips? A quick search gives me half of them are long distance (50+ miles).

Since the short trips can all be done very efficiently on battery (recovering all the braking, too), I guess the weight isn't much of an issue for commuting if you can have the rest -half of the total driven miles- on EV with a full battery vehicle.

I wish I could find numbers on eCO2/miles for the short vs long trips.
